AUTOMATIC CUT-OFF FOR GASOLINE TANKS AND THE LIKE.

. Application filed December 14, 1921. Serial 170.522,!371.

To all whom it may concern:

Be it known that I, ADAM H. GINSBACII,

a citizen of the United States, residing at Huntington Park, in the county of Los Angeles and, State of California, have invented new and useful Improvements in Automatic C'ut-Ofl's for Gasoline Tanks and the like, of which the following is a specification.

My invention relates to closure caps for liquid containers, and a purpose of my invention is the provision of a closure cap for gasoline tanks and the like having incorporated therein an automatic cut-oil" which operates to'allow of the admission of air to the tank, while at the same time preventing the discharge of gasoline therefrom.

I Willdescribe one form of closure cap and cut-ofl' embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings,

Figure 1 is a sectional view showing a portion of a tank and having applied thereto one form of closure cap and automatic cut-ofl' embodying my invention.

Fig. 2 is a detail view of the cap shown in Fig. 1. 3o

cluding the cut-off shown in the preceding views. I

Referring speciflcallyto the drawings in which similar reference characters refer to similar parts, my ingfiintion, in its prelferred embodiment, c prises a cap designated generally at K and including a convex top portion 15 provided at its periphery with a depending annular flange 16, and an annular shoulder 17 at the point of connection between the flange and the top portion. The flange 16- is exteriorly threaded to permit of its application to an opening R of a tank T, and a washer 18 is adapted to be interposed between the shoulder 17 and the upper edge of the opening R toprovide a liquid-tight seal, as will be understood.

Secured to or formed integrally with the flange 16 is a spider S constructed in the manner shown in Fig. 3. The center of this spider is adapted to form the bearing for the lower and reduced end 19 of a post 20. As shown in Fig. 1 a float F, formed of cork or any other suitable material, is rigidly sustained on the post 20 and in such Fig. 3 is a bottom plan view of 'a cap in i manner as tobe disposed wholly within the cap K. The upper end of the post 20 is constriicted to provide a valve 21, and projecting upwardly from this valve is a stem 22 designed to guide the valve in its vertical movement into a seat 23 formed in the top portion 15.--

In all closure caps for gasoline tanks and the like it is necessary in order to effect the, proper dispensing of gasoline from thc tank to provide an air inlet in the closure cap. To this end the top ortion 15 is provided with a duct 24 which communicates with a second duct 25 disposed at right angles to the first duct and formed in an operating flange 26, constituting a part of cap K, and designed for the pur posedof rotating the cap as will be understoo The valve seat 23 constitutes the inner end of the duct 24, and the valve 21 is clesigned to control the passage of air or liquid through the duct 24, and consequently the duct 25.

In the operation of the automatic cutoff the valve 21 is normally in open position under the action of gravity, thereby allowing of the influx of air into the tank through the ducts 24 and 25. However, when the tank T is tilted or otherwise moved to cause the gasoline within the tank to be moved into the cap K the float F is automatically elevated, thus imparting a corresponding movement to the valve 21 to close the inner end of the duct 24. This obviously prevents the escape of gasoline from the duct 24 so that it is confined within the tank and the wasting of the gasoline is thus prevented. It will be un derstood that as soon as the gasoline leaves the cap and returns to the tank the float will automatically descend, thus actuating the valve 21 so as to open the duct 24 to again admit air into the tank.

Although I have herein shown and described only one form of closure cap and automatic cut-off embodyingmy invention it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

What I claim is:

1. A device of the character described, comprising a closure cap including a top portion having a duct formed therein, an

operating flange having a duct therein communicating With the first duct, a spider sustained on the cap, a post movable on the spider, a float carried by the post, and a valve formed on the post and controlling the first ductfor the purpose described.

2. A device of the character described, comprising a closure ca including a top portion having a duct ormed therein, an operating flange having a duct therein at right angles to and communicating with the first duct, a spider sustained on the cap, a post movable on the spider, a float carried by the post, a valve formed on the post and controlling the first duct for the purpose described, and a stem on the valve end of the post for guiding the valve in its movement to control said duct.

In testimony WhereofI have signed my name this specification.
